Where do the tank vent lines go?

I think the fuel is just flowing over the vent tubes in the tank. But I am getting what i think is an abnormal amount of tank pressure. A new cap is on the way. First we trey both vents open. If drips then we close off each and see. I am also wrapping the rear and sides of the tank for heat. ya neve know. I am thinking these tanks were just a crappy design
